With the aim of addressing problem trajectory tracking control quadrotor unmanned aircraft robots (UARs), in this study, we developed a neural network and event-triggering mechanism-based adaptive scheme for UAR system. The main technologies included are as follows. (1) Under condition that only quadrotor’s position information can be obtained, modified high-gain state observer-based dynamic su...

This paper discusses the finite time consensus (FTC) issue of nonlinear heterogeneous multi-agent systems (HMASs) by combining integral sliding-mode control (SMC), event-triggered (ETC) and pinning methods. The SMC is constructed separately for first-order second-order agents to assure that system not interfered nonlinearities disturbances when state trajectory moves on sliding surface. To stim...

this paper addresses the design of an observer-based fault diagnosis scheme, which is applied to some of the sensors and actuators of a wind turbine benchmark model. the methodology is based on a modified sliding mode observer (smo) that allows accurate reconstruction of multiple sensor or actuator faults occurring simultaneously. the faults are reconstructed using the equivalent output error i...
